1 Crown - Elizabeth II H.M.S. Victory

HMS Victory had been rotting at her Portchester Creek moorings for years when a 1921 survey declared her structurally beyond saving. The decision to preserve her permanently in dry dock at Portsmouth — finalized in 1922 — was driven largely by pressure from the Society for Nautical Research, which launched a public fundraising campaign that ultimately raised £140,000. She remains the oldest naval vessel still in commission, carried on the Royal Navy's books as a shore establishment.

The Isle of Man issued Crown-sized commemoratives aggressively through the early 1980s, with Pobjoy Mint producing the bulk of them under contract.
